Emergency in the US: A powerful winter storm swept across large parts of the United States over the weekend, triggering widespread flight cancellations,
power outages and hazardous road conditions. Authorities warned that the impact could last several days as heavy snow, sleet and freezing rain continued to batter multiple states. Nearly 140 million people -- over 40 per cent of the US population -- were placed under winter storm warnings, stretching from New Mexico in the south to New England in the northeast.
